.. Serious electronic literature (for scholarship, detailed controversy and detailed collaboration) must support bidirectional and profuse links, which cannot be embedded; and must offer facilities for easily tracking re-use on a principled basis among versions and quotations.
Xanalogical literary structure is a unique symmetrical connective system for text (and other separable media elements), with two complementary forms of connection that achieve these functions-- survivable deep linkage (content links) and recognizable, visible re-use (transclusion). Both of these are easily implemented by a document model using content lists which reference stabilized media.
This system of literary sturcture offers uniquely integrated methods for version management, side-by-side comparison and visualizable re-use, which lead to a radically beneficial and principled copyright system (endorsed in principle by the ACM (38(. Though dauntingly far from the standards which have presently caught on, this design is still valid and may yet find a place in the evolving Internet universe.
Is it too late? Would it mean just too much overhead? We believed that like the hidden overhead of the Internet itself, such a structure will pay for itself manyfold.
We can see no other important agenda for hypertext.
